VACUUM-DISCHARGE APPARATUS.

Speeification of Letters Patent.

Patented Aug. 23, 1921.

To all whom it may concern:

Be it known that I, HERMAN HEUsnR, a citizen of the United States, residing at 929 Sheridan road, Evanston, in the county of (look and State of Illinois, have invented a new and useful Improvement in Vacuum- Discharge Apparatus, of which the following is a specification.

The present invention relates to vacuum discharge apparatus, and more particularly to apparatus intended to effect the discharge of liquid. from a system such as an evaporating or dealcoholizing system, wherein a vacuum is maintained.

in order that the invention may be clearly understood a specific embodiment thereof is shown in the drawing, in which the figure shows an elevation of an apparatus constructed in accordance with the invention.

Referring more particularly to the drawing the numeral 5 indicates the discharge line from a vacuum apparatus, for example, the condenser of an evaporating or dealeoholizing system. By a suitable angular fitting 6, the discharge line is connected to the intake 7 of a wet vacuum pump 8 of any suitable type shown in end elevation. The vacuum pump 8 discharges through pipe 9 and the dowrnvardly extending pipe 10 into the funnel shaped top 11 of the pipe 12 leading to any suitable collecting means. The top of the tunnel shaped opening 11 is covered with a screen 13 to permit the free escape of the air or gas accon'manying the discharge liquid.

The discharge pipe 5 is provided with a liquid gage 1 1, the upper end of which is con.- nected to the discharge pipe at a point 15 above the intake of the vacuum pump. The lower end of the gage 14: is connected to the pipe 5 by means of a fitting 16 at a point below the intake of the vacuum pump. The

fitting 16 may be also provided. with a trycock 17.

The liquid gage 14. is thus so located that the level of the liquid on the intake side 0:1. the wet vacuum pump can be readily ob served. In the actual operation of the apparatus, it is essential to the successful functioning of the vacuum appa 'atus to which the pump is attached, and to the mainte nance of a vacuum therein, that the liquid level in the discharge pipe shall not rise above the level of the intake of the pump except momentarily. If this should occur, the pump would draw liquid only and the efficiency of the vacuum apparatus would be seriously impaired. Furthermore, when a liquid seal is permitted to form and to rise in a condenser pipe from a vacuum dealcoholizer, as illustrated, in the present case, an increase in pressure in the evaporating sys tem is caused. This is particularly the case when cooling is effected in the condenser by the direct contact of the evaporated vapors with the cooling medium. By means of the gage let the liquid level may be observed and the proper control applied to maintain it at a point below the top of the intake pipe 7.

Although the present invention has been described in connection with certain details of apparatus, it is clearly i'lnderstood that these details are not intended to be regarded as limitations upon the scope of the invention, except in so far as included in the accomp anying claim.

I claim:

In combination, a discharge line, a vacuum pump, the intake of which is directly connected to the (:lischarge line and a liquid connected to said discharge line at points above and below the intake of the vacuum pump.
